Title: A Process for Producing Heavy Hydrocarbon Oils Having Less Odor Vapors and Harzardous Substances Using Used Oils' Distillation Residues
Inventor: CHO JOUNGMO
IPC: B01D17/00
Filed: 2020-01-09
Abstract: The present invention relates to a method for removing substances causing hazardous components including a plurality of types of odors, fine dust and the like in the heavy oil fractions so as to prevent generation of hazardous components including odor, fine dust and the like, which can be generated in a process of using heated heavy oil fractions as a raw material. In addition, in removing vapor, including odor-causing and hazardous components, from heavy oil fractions, the present invention improves heavy oil fractions and provides a use place for used oil by using distillation residues generated during a used oil purification process. Heavy oil fractions treated according to the present invention can improve working conditions in industries of using heavy oil fractions as a raw material and can greatly reduce hazardous substance generation in the industries. In addition, heavy oil fractions improved according to the improving method do not largely affect the characteristics thereof as a heavy oil raw material since a small amount of low boiling point component is only separated and pyrolysis or chemical reaction of molecular structures in oil fractions does not dominantly occur. Furthermore, since refuse-derived fuel which is a low cost separated material generated in a used oil purification process is used as a dispersing agent for removing hazardous components of the heavy oil fractions, the present invention can improve economic feasibility of a heavy oil fraction improvement process and save costs for treating used oil.
